<p>A case (1) for a stick product that prevents the release of the stick product from the holder cup (20) comprises an inner sleeve (2) having a wall (5) and a longitudinal track (6) within the wall. The longitudinal track has a first upper lateral segment (30) and a second upper lateral segment (35), said first upper lateral segment having a ramp (31). An outer sleeve (10) is fitted about the inner sleeve (2) so as to be able to rotate with respect to the inner sleeve, said outer sleeve having an inner wall (13), an outer wall, and a helical track (15) along the inner wall. A holder cup (20) is fitted into the inner sleeve and comprises a shell (22) having an inner surface (23) and an outer surface (24). A lug (21) is attached to the outer surface and extends through the longitudinal track (6) to engage the helical track (15). A bellows portion (25) is located below the lug (21) and comprises part of the shell of the holder cup, said bellows capable of occupying a first stretched position (fig. 2A) and a second contracted position (fig. 2B). When the bellows is in the stretched position, the stick product can be easily inserted into the holder cup without damaging the stick itself. In the contracted position, the bellows forms ridges (40) which grip and penetrate the stick product, thus holding the product in place.</p> |
